BRAKE FOR PERAMBULATORS.

To all whom it may concern:

Be 1t known that I, CLIFTON WEST, a subj ect of His Majesty the King ofGreat Britain, 5

and resident of The Gates, Oarters Lane, Poole, county of Dorset, inEngland, have invented certain new and useful Tmprovements in BrakingMeans for Perambulators, Mail- Oars, and. Like Vehicles, and of whichthe following is a specification.

This invention relates to improved braking means for perambulators,mail-cars and like vehicles, and has for its object to provide a simple,inexpensive and effective arrangement which can be readily attached tovehicles of the kind referred to and be operatable within the range of asmall child. Preferably the braking arrangement is set up upon a plateor bracket so that it is only necessary for fitting the brake to fixsuch late or bracket to some convenient part of t 1e vehicle, allowingof course for the proper opera tion of the brake parts.

To adapt one stock mechanism for vehicles of the kind referred toirrespective of the varying spaces occurring within reasonable limitsbetween the peripheries of the wheels and the sides of the vehicles, Iprefer to provide that the brake shoe arm shall be variable in length atwill.

I/Vith the foregoing and other objects in view I will proceed todescribe my invention with reference to the accompanying sheet ofdrawings in which:

Figure 1 represents a side view of a mail car showing in. full outlinethe preferred arrangement of my invention applied thereto. Fig. 2 is anend view of the car and braking means therefor. Figs. 33, 4 and 6 showembodiments of the invention according to the arrangement thereofpreferred as aforesaid. Fig. 5 is a detail view to be hereinafterreferred to.

In carrying the invention into effect, I provide a conveniently shapedplate or frame a of metal, wood or other suitable material adapted to bereadily attached to the side or other part of a mail-car or like vehicleas by means of bolts, screws, clamps or other appropriate devices. Uponsuch plate or frame a I pivotally mount a brake lever 72, one endthereof on one side of the pivot c carries a brake shoe (Z and the otherend thereof on the other side of the said pivot is adapted to beoperated upon by a cam such as c. This cam e referring to Figs. 1 and 3is mounted in fixed Specification of Letters Patent.

connection upon a stud shaft f revolubly secured to the plate a, so thatby rotating the said shaft f as by means of a hand lever g, the cam cturns with the shaft and imparts pivotal movement to the brake lever b.

Preferably the brake-lever Z) is bent horizontally at 77 for economizingspace and such part b may conveniently be grooved for permitting theperiphery of the cam to engage therein and so obviate lateral play ofthe brake-lever.

The brake lever l) as shown is placed under the influence of a springsuch as 7L either operating to pull (as shown) or press over thebrake-lever to bring the brake-shoe into contact with the wheel whenpermitted so to do by the position of the cam e.

In lieu of the cam being fixed to the stubshaft f, it may as shown inFigs. 4 and 6 be revolubly secured to the stub-shaft fixed to the plateor frame a in which case the cam may then have formed integral therewithor otherwise connected thereto a handle i which may be bent outward at ito give the requisite freedom ior manipulating the same and to allow itto clear the spring h if necessary.

As shown in Fig. 5, the brake shoe arm 5 projecting at right angles tothe brake-lever b is arranged variable in length by dividing said armand adj ustably connecting the inner ends of the divided portionstogether by a sleeve threaded internally right and left handed forengaging the inner ends of the divided portions similarly threaded externally. Obviously however other modes of arranging that the brake shoearm is variable in length at will may be adapted, whereby the varyingdistances within reasonable limits between the wheels and the bodies,etc. of different vehicles may be quickly compensated. The brake shoealso may be adjustably connected to the brake-shoe arm if desired.

To protect the braking means from the weather, a suitable case or cover7c (Fig. 6) may be provided adapted to be detachably connected to theplate or frame a, for wholly or partly inclosing the parts thereon, thebrake lever l), and the handle (g, i), when employed as the medium foroperating the cam 6, working in slots in the sides of said cover. Or thehandle (g, i) may be arranged to work in front of the cover (as shown inFig. 6) thus preventing any slotting of the top thereof.

Having thus described my invention what I claim and desire to secure byLetters Patent 1SI 1. In perambulators, mail cars and the like vehiclesa plate attachable to a convenient part of the vehicle, said platehaving mounted thereon a braking mechanism comprising a pivoted leverhaving a brake shoe, a cam mounted on a stub shaft revolubly secured tothe plate, said cam being adapted to be operated by hand and cooperatingwith said lever, and a spring for imparting pivotal movement to thebrake lever substantially as herein described.

2. In perambulators, mail-cars and the like Vehicles a plate attachableto a convenient part of the vehicle, said plate having mounted thereon abraking mechanism comprising a pivoted lever variable in length andhaving a brake shoe, a cam mounted upon a stub shaft revolubly securedto the plate, said cam being adapted to be operated by hand andcooperating with said lever and a spring for imparting pivotal movementto the brake lever substantially as herein described.

3. In perambulators, mail cars and the like Vehicles the combination ofa plate attachable to a convenient part oi the vehicle, a cover adaptedto be detachably connected to said plate, braking mechanism mounted uponsaid plate comprising a pivoted lever having a brake shoe, a cam adaptedto be operated by hand and cooperating with said lever, and a spring forimparting pivotal movement to the brake lever substantially as hereindescribed.

4. In perambulators, mail cars and the like vehicles, the combination ofa plate attachable to a convenient part of the vehicle, a cover adaptedto be detachably connected to said plate, braking mechanism mounted uponsaid plate comprising a pivoted lever variable in length and having abrake shoe, a cam adapted to be operated by hand and cooperating withsaid lever and a spring for imparting pivotal movement to the brakelever substantially as herein described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
